The present invention concerns an arrangement for portioning out paste,cream and other materials of a similar cor'lsistency, and among otherobjects of the invention it aims at the amelioration of the hygienicalconditions connected with the use of toothpaste. When using toothpastecontained in toothpaste tubes of the types generally used it isdifficult to prevent the mouth of the tube from touching the toothbrush,when the toothpaste is porti'oned out. In families where the same tubeis used by several persons the said contact implies of course notincon'siderable risks for the transfer of germs from the toothpaste tubeto the toothbrush or from the brush to the tube. The handling of thetoothpaste tube including the screwing off and on of the protectivecover and the rolling together of the tube so as to press the pasteagainst the mouth of the tubeoften implies considerable waste of time.To make the threadsof the protective cover fit into those of thetoothpaste tube is also often a source of irritation.

One of the objects of the present invention is to remove thesedisadvantages.

The invention is essentially characterized by the fact that thearrangement consists of a stand to be applied to a wall e. g., in whichstand there is arranged a piston rod, actuated by a system of levers,and itself actuating a piston or pressing disk; the stand being providedwith a reception arrangement fora tube, open at its top, and at itsbottom end provided with a relatively narrow outlet, in which tube thepiston or the pressing disk can move in such a way that at an actuationfrom the outside of the system of levers the piston rod and with it thepiston is displacedin the direction of the bottom of the tube appliedinto the stand and presses out a portion of some paste or similarmaterial inclosed into the tube between its bottom and the piston or thepressing disk; These as Well as other characteristics of the inventionwill be fully explained in the following description of an arrangementfor portioning out toothpaste, shown on the drawing andconstructedaccording tothe idea of the invention.

Fig. 1 shows the arrangement seen from one side and partly as a section.Fig. 2 is a section along the line II'II of Fig. 1 at which a form ofrealisation of a holder for a tube or receptacle containing the paste isshown. Fig. 3 shows a closing device belonging to the arrangementprovided with acutting off knife or thread for the string of pasteportioned out from the tube.

l denotes a bracket orstand, which by means of: an arm 2 is applied toa: solid frame e; g. a

wall. A sliding piston rod 4 rests in and is guided by a hole 3 goingright through the stand, which piston rod also passes through a cover 5,applied on the upper side of the stand. At its upper end the piston rodis provided with a disclike contrivanoe 6. i denotes a tube or containermanufactured of impregnated cardboard or other material resistantagainst the paste used, in which container the paste is inclosed. At theinterior side of its upper end the tube or container is provided with asoft ring 8 of cardboard, which presses all around the interior part ofthe easing surface of the stand I. The disk 6 rests against a piston orpressin disk 9, the diameter of which tallies with the interior diameterof the container. The space of the container below the piston is filledwith paste Hi, which at the portioning out movement of the piston rodwill be pressed out through an outlet gate II' jp'rovided in the bottomof the container. A thread spring 12 bent into the shape of a Taccording to Fig. 2 rests in three holes provided right through thelower part of the stand, the ends H! of the thread being pressed intothe soft cardboard ring 8 by the piston rod, by means of whichcontrivance the container 1 is firmly afiiixed to the stand I. When thecontainer is to be changed the piston rod is lifted so high that acontracted part Id of the lower end of the piston rod comes on the samelevel as the thread I-2 when the shanks I2 of the thread, whichelastically press against the piston rod, enter into the contracted partIt, thus causing the ends l3of the shanks to be drawn out of thecardboard ring 8. The container can then be removed and replaced with anew one. On pressing down the piston rod the shanks l2 will be removedfrom each other on account of the diameter of the piston rod increasingat the place where the arms press against the rod. The ends l3 will thenbe pressed out into the cardboard ring 8 and due to that fact thecontainer will be firmly attached to the stand.

The portionin out movement of the piston rod is caused by a pressingforce being applied to the inferior part I6 of thelevcr I 5, whichinferior part in this case is provided with a notch for a toothbrush ll.On applying the pressing force the lever I5 turns round a pivot I8 fixedto the holder 2. Above the pivot it the lever is developed into theshapeof a T, one end ofthe crossbeam of the T being charged with a spiralspring 22, while the other end is provided with an adjusting screw 2 I.This screw rests againsta plate or disk 23, loosely passed over thepiston rod 4 and resting on a spiral spring 24 pressin against thestand. At the turning movement mentioned above of the lever I5 thespiral spring 22 is stretched. At the same time the point of theadjusting screw 2| presses against the disk 23, which then on account ofthe eccentric load assumes an oblique position, so that the oppositeedges of the hole of the disk press against the piston rod. At thecontinued effect of the pressure of the adjusting screw on the disk 23the latter transfers the pressing force to the piston rod by means ofthe friction engendered between the edges of the hole of the disk andthe rod, the latter consequently being pressed downwards. When theexterior pressing force at the end of the lever I6 is removed the spiralspring 22 carries the'system of levers back to its original position. 25denotes an arm supporting a shutting arrangement. One end 26 of the arm25 is-seen from above according to Fig. 3-developed into the shape of aT. In the arm l5 there is provided a slot through which the lever 25passes. At the back of the lever l5 the protruding arms of the T-shapedend part rest in notches 21 provided for them in the lever l5. The arm25 is kept in the said notches 2! by a spring 28 arranged on the leveri5. 29 denotes a shutting and opening device, the upper side of whichcovers the outlet gate II. The device 29 rests on the arm 25 in such away that its upper side is allowed the liberty of movement required toattain a good fitting in around the gate I I. Outside the device the arm29 is developed into two arms 3!] and 3!, between which there isarranged a cutting knife or thread 32 for cutting on? the paste pressedout. When the toothbrush I? presses against the end It of the lever [5the device lays open the gate 29, and the thread 32 passes it, whereuponthe edges of the disk 23 are caused to catch the piston rod 4. On thecontinued pressing movement of the toothbrush ll the piston rod ispressed downwards and the pressing force is transferred to the piston orthe disk 9, which in its turn presses against the exerts a pressure onthe system of levers so that the end It of the lever follows thereceding movement of the toothbrush ll. When the cutting off thread 32passes the gate H, the pressed out amount of paste is separated from thecontents of the container 1, whereupon the shutting device 29 goes backto its, original position and shuts the gate H. By the present inventiona contrivance for portioning out toothpaste and paste of other kinds hasapparently been provided, by means of which a very rapid and convenientfeeding and portioning out of the paste is obtained, which advantagesalso comply with the highest demands for hygienical conditions.

The invention is of course not restricted to the form of realizationshown and described, but it can be varied in several different wayswithout differing from the idea of the invention, Thus for instance thetube or the container can be made movable in relation to a firm systemof arms. The contrivance can be used for portioning out all kinds ofpaste, cream and similar products, where the advantages of the inventionwill be apparent. One form of realization for instance is intended to beused for hand paste,

4 used for cleaning purposes. At such forms of realization which areintended for hand paste the arm 25 can suitably be given the shape of along strip of plate, the outer end of which is developed into a terminalshort down bend, serving to prevent the accumulation of paste on it.

The arrangement shown and described for attaching the tube or thecontainer to the stand can of course be replaced with any otherarrangement of attaching. It can be given the form e. g. of a screw cap,a bayonet fixture or some similar contrivance.
